I would be careful of that, because social security caught wind of me doing some volunteer work (because of something I mentioned to a doctor) and that was one of the reasons I was denied. They figured that if I "worked" for free, I could work for pay.

Also, having any kind of social life at all, is cause for denial along with doing anything beyond just sitting and staring off into space. You can't go shopping, or clean your bathroom either.

p.s. my GAF score is 45.
